Abzorb is as much about avoiding things as it is about collecting them. You’re put in control of an arrow with two separate perimeters. The innermost perimeter is your defense. Don’t allow any object to touch it. The outer perimeter acts as your absorbing mechanism. Anything within its confines will be absorbed. Get close to the blue orbs to collect them. Keep away from the red orbs to avoid losing points. Move quickly because your score is based on the time it takes to consume all of the blue orbs. The game includes 80 levels, customizable controls, and online leaderboards.
